What I'm looking for

I’m looking for a role where I can contribute to an established design pipeline and a high-standard production lifecycle, delivering user-centered product design, scalable design systems, and front-end-ready prototypes that preserve design intent.

I’m a Senior Product Designer with over 20 years bridging design and engineering. I specialize in design systems contribution, prototyping, and product strategy, translating complex problems into high-impact, positive UX.

For 16 years, I founded and led a full-service digital agency (Nuvizus Communications), owning products end to end from SWOT and PRD definition through deployment. I led user-centered design and delivery across news media, broadcast, banking, and enterprise software—building durable solutions that kept design intent intact through development.

Over the past five years, I’ve focused on UX consulting and scalable design system contribution in startup environments. I seek a role where I can contribute to an established design pipeline and a high-standard production lifecycle—using systemic validation and documented, front-end-ready prototypes to ship confidently.
